Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In order to clearly illustrate the technical solution of the embodiment of the present invention, referring to fig. 1, which shows a LCD screen structure adopted in most of the related art at present, it can be known that the LCD screen structure at present may include, from inside to outside: as shown in fig. 1, light emitted by the backlight source is polarized after being transmitted and refracted by the functional layer of the LCD structure, and although the naked eye cannot distinguish whether the light is polarized, the polarized light is output when the polarizer is worn, such as polarized glasses worn during driving or polarized glasses worn during viewing 3D video. If the polarization direction of the polarized light output by the LCD is exactly the same as the filtering direction of the polarizer, the content displayed on the LCD screen cannot be seen clearly when the polarizer is worn.
In view of the above problem, an embodiment of the present invention provides a terminal device 20, and referring to fig. 2, the terminal device 20 may include: a controllable light rotating film 201, a controller 202 and a driver 203 which cover the outer layer of the LCD screen;
in detail, the outer layer of the LCD screen is an external polarizer, and therefore, referring to fig. 3, in a specific implementation process, the controllable light-rotating film 201 may cover the external polarizer of the existing LCD screen structure, and the controllable light-rotating film 201 may be made of materials such as spiral polyurethane, polylactic acid, or polylactic acid copolymer, which all have a spiral macromolecular structure, and therefore, the controllable light-rotating film 201 may include a plurality of optically active molecules. Referring to the enlarged view shown by the circle in fig. 3, both the upper and lower sides of the controllable light-rotating film 201 can be connected to the transparent electrode, and the inclination angle of the light-rotating molecules in the controllable light-rotating film 201 can be changed by applying different voltages to the controllable light-rotating film 201, so as to adjust the angle of the polarized light output by the screen, that is, the rotation angle of the light-rotating molecules in the controllable light-rotating film 201 corresponds to the polarization angle of the light output by the controllable light-rotating film;
for the controller 202, it may be configured to:
acquiring current state parameters of the terminal equipment;
inquiring a corresponding relation between a preset state parameter and a polarization angle according to the current state parameter, and determining the polarization angle corresponding to the current state parameter;
transmitting the polarization angle corresponding to the current state parameter to the driver;
specifically, the controller 202 may be provided separately and connected to a Micro Control Unit (MCU) of the terminal device; or multiplexing with an MCU of a terminal device, so as to obtain a current state parameter of the terminal device, and determine a polarization angle corresponding to the current state parameter, where the polarization angle refers to a polarization angle obtained by changing the inclination angle of the optically active molecule by the controllable optically active film 201. In the embodiment of the present invention, the controller 202 or the MCU of the terminal device may be an integrated circuit chip having signal processing capability. Such as a general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Digital Signal processing Device (DSP Device, DSPD), a Programmable Logic Device (PLD), a ready-to-use Programmable Gate Array (FPGA) or other Programmable Logic Device, discrete Gate or transistor Logic, discrete hardware components.
For the driver 203, it may be configured to: and driving the rotation angle of the optically active molecules in the controllable optically active film 201 according to the polarization angle corresponding to the current state parameter.
Specifically, the driver 203 may be an application specific Integrated Circuit (IC) to drive a voltage applied to the optically active molecules in the controllable optically active film 201 to control the rotation angle of the optically active molecules.
With the liquid crystal display device 20 shown in fig. 2, by covering a controllable light-rotating film on the outer side of the LCD screen of the terminal device, the polarization angle of the controllable light-rotating film can be adaptively adjusted according to the current state parameters of the terminal device, the polarization direction during the production of the LCD screen does not need to be strictly controlled, and the problem of brightness reduction when wearing a polarizer due to circularly polarized light adjusted by a birefringent material is avoided. The user can still clearly view the LCD screen at various viewing angles without affecting the use of the LCD screen device while wearing the polarizers.
For the technical solution shown in fig. 2, in the daily use process of the user, the scene needing to wear the polarizer mainly includes: when driving in sunny weather, the polarizer is worn to filter out reflected glare on the ground, or in the process of watching 3D video, the 3D glasses are worn to form two different images on the left eye and the right eye. Based on these two scenarios, the technical solution shown in fig. 2 can be implemented according to the following two cases.
In the first case, when a user drives a vehicle by wearing a polarizer, the light reflected by the ground is partially polarized due to brewster's law, and the polarization direction of the reflected light from the ground is generally horizontal. Therefore, the polarizer worn during driving is mainly used for filtering the polarized light in the horizontal direction, and the polarized light in the vertical direction is reserved. The principle of the polarizer filtering out the horizontally polarized light can be seen from fig. 4, in fig. 4, the dotted arrow indicates the propagation direction of the light, so it can be known that, when a user wears the polarizer to view the display content of the terminal device during driving, for example, to view the navigation content and the communication content in the terminal device, if it is desired to make the viewing effect of the user not affected, it is necessary to ensure that the polarized light output by the terminal device through the LCD screen is always maintained in the vertical direction. Based on this, in one possible implementation,
the controller 202 is configured to obtain current sensing data;
determining the inclination angle of the terminal equipment relative to a user based on the current sensing data;
and determining a negative angle corresponding to the inclination angle of the terminal equipment relative to the user as a polarization angle corresponding to the current induction data.
Correspondingly, the driver 203 is configured to:
and driving the rotation angle of the optically active molecules in the controllable optically active film 201 according to the polarization angle corresponding to the current sensing data.
For this implementation, referring to fig. 5 in particular, it is preferable that the tilt angle of the terminal device relative to the user be determined by sensing data of the gravity sensor, since the gravity sensor outputs component information of three directions x, y, and z, the current tilt angle of the terminal device can be obtained by calculating the component information of the three directions, and the angle of rotation of the image is affected only when the terminal device rotates around the z-axis, so the controller can determine the tilt angle α of the terminal device relative to the user based on the current sensing data obtained by the gravity sensor, and only the components of the two directions x and y are needed in determining the tilt angle α.
In the driving mode state, after determining the inclination α of the current terminal device relative to the user, the rotation angle- α of the optically active molecules of the controllable optically active film 201 can be controlled to output uniformly, so that the terminal device can be ensured to have a vertical polarization direction of the output light no matter what angle the terminal device is at.
In the second case, when the user wears the 3D glasses, the output image of the LCD screen needs to have a 3D effect, and at this time, images need to be output to the left and right eyes of the user respectively, for example, when playing a 3D movie, left and right eye contents are distributed according to a film source; when information such as desktop icons and the like is displayed, the icons are foreground, the canvas is background and the like according to a foreground and background separation principle, and details are not repeated in the embodiment of the invention. In this case, therefore, unlike the above-described case, a uniform rotation angle cannot be set for all the optically active molecules, and it is necessary to set the rotation angle for the arrangement of the optically active molecules individually. Thus, in one possible implementation, the optically active molecules in the controllably optically active film can be divided into an array of optically active lattices, made up of at least one optically active lattice, by pixel size; after the optically active molecules are divided into the optically active lattice array, the rotation angle of the optically active molecules can be adjusted to the rotation angle of the rotating lattice.
The controller 202 is configured to obtain an operation state parameter of the terminal device corresponding to the division of the optically active molecules into optically active lattices;
and indicating that the terminal equipment is in a 3D playing state corresponding to the running state parameters, and determining the polarization angle of the 3D playing state.
Correspondingly, the driver 203 is configured to: driving the optical rotation lattice rows of the optical rotation lattice array to output optical rotation angles of 0 degree and 90 degrees according to the polarization angle of the 3D playing state;
or, the optical rotation lattice rows of the optical rotation lattice array are driven according to the polarization angle of the 3D playing state to output the optical rotation angles of 0 degree and 90 degrees according to the row spacing.
Specifically, in order to realize that the left and right eyes output images respectively, and therefore, the polarization directions of the two images are 0 degree and 90 degrees respectively, when the controller 202 can determine that the terminal device is currently in the 3D playing state, the driver 203 can be instructed to drive the optical rotation lattice array to drive and output 0 degree and 90 degree at intervals of the optical rotation lattice row; or the controller may instruct the driver 203 to drive the optically active lattice array to drive the output 0 degrees and 90 degrees at intervals of the optically active lattice column. Referring to fig. 7, the optical rotation lattices may be arranged in a matrix and connected in a circuit, and the driver 203 applies a control voltage to each optical rotation lattice through row and column coordinates based on an instruction of the controller 202 to control the rotation angle of the lattice molecules. Referring to the effect illustration shown in fig. 8, taking the terminal device in the landscape state as an example, each small box represents an optical rotation lattice obtained by dividing optical rotation molecules by pixel-level granularity, in fig. 8, the driver 203 drives the optical rotation lattice array to drive and output 0 degrees and 90 degrees at intervals according to the optical rotation lattice column, so that the terminal device LCD screen can output polarized light in orthogonal directions, and then when the polarization directions of the left and right lenses of the 3D glasses are orthogonal, different images can be output on the left and right eyes of the user.
Based on the terminal device 20, referring to fig. 9, which shows a display control method provided by the embodiment of the present invention, it should be noted that the method is applied to a device having an LCD screen, specifically, the terminal device may be the terminal device mentioned above, and the outer layer of the screen is covered with a controllable optical rotation film, the controllable optical rotation film includes optical rotation molecules, and the rotation angle of the optical rotation molecules corresponds to the polarization angle of the output light of the controllable optical rotation film, specifically, the method includes:
